The study assessed the effects of a life skills-based health empowerment intervention on resilience among adolescents in Purulia, India using a Solomon four-group design. 742 adolescents were assigned to experimental and control groups. The experimental group received an intervention focusing on life skills and health topics. Resilience, internal health locus of control, and self-determination significantly improved in the experimental group compared to controls following the intervention. The intervention was particularly effective at increasing resilience among tribal adolescents.

12. Effects of health empowerment intervention on
resilience of adolescents in a tribal area: A
study using the Solomon four-groups design
(good title)

13. ABSTRACT
Rationale: Resilience prevents the emergence of stress-related mental health problems among adolescents. Adolescents in
tribal areas of India are more prone to develop such problems.
Objectives: The primary objective was to determine the effect of combined life skills-based health empowerment
intervention on the resilience of school-going adolescents in a tribal area. The secondary objectives were to determine the
effect of the intervention on internal health locus of control and self determination and to compare the effect of
intervention on resilience between non-tribal and tribal adolescents.
Methods: We conducted this quasi-experimental study using a Solomon four-group design among 742 adolescents in two
schools of Purulia, West Bengal, India. Students of the pretested group were examined for resilience using the Child
Youth Resilience Measurement scale. A life skills education-based health empowerment intervention was administered
among students of the experimental group. Post-test data on resilience, self-determination, internal health locus of control
and pathological behaviour was obtained 3 months after the completion of intervention. A multi-level general linear
mixed model was constructed to determine the effect of intervention on resilience.
Results: Resilience was less among tribal adolescents at baseline. The intervention significantly improved resilience
[βAdjusted = 11.19 (95% CI ¼ 10.55, 11.83], with a greater increase for tribal adolescents [βtribal-nontribal = 1.53 (95%
CI ¼ 0.03, 3.03)]. The intervention also significantly improved internal health locus of control (marginal mean increment
1.38 ± 0.05), self-determination (marginal mean increment 3.71 ± 0.09) and reduced pathological behaviour of the
adolescents.
Conclusion: Our study informed the current health policy that the existing life skills education-based programme should
be reviewed and modified to include generic life skills, and the life skills education-based programme should be coupled
with developmental interventions aimed at improving adult education and family climate for optimum effect on mental
health and health behaviour of adolescents.

14. INTRODUCTION

15. • Mental health problems are linked to the negative affect state and
unsuccessful coping in the presence of stress
• Indian adolescents residing in tribal areas are exposed to an even
greater risk of developing stress-related mental health problems
• They face greater adversity in life course and are deprived of even the
basic amenities

16. • Threats and stressors: poverty, violence, disaster and war
• Low stress resilience in adolescence is associated with greater risk of
receiving medications for depression and anxiety in middle age
• Empowerment has been shown as an effective method to increase
resilience

17. • Strength-based approaches focus on local capacity building by
attending to inherent resources or strengths of individuals, families,
groups or organizations ‘deploying personal strengths to aid recovery’
• Popular form of strength-based intervention is life skills education
• Success of LSE depends on the fidelity of implementation

18. • To inform the current health policy regarding the effect of a short-term
modified LSE-based empowerment intervention on the resilience of
school-going adolescents
(scientific background and rationale well explained)

19. • Primary:
 To determine the effect of combined life skills-based health
empowerment intervention on the resilience of school-going
adolescents in a tribal area
OBJECTIVES

20. • Secondary:
 To determine the effect of the intervention on internal health
locus of control and self determination
 To compare the effect of intervention on resilience between non-
tribal and tribal adolescents

43. Data source:
• Secondary data: School academic record used to assess the academic
performance of the students in the previous annual examination

44. INTERVENTION
• Intervention module had two parts:
 Basic life skills (adapted from intervention module of Adolescent
Girl Empowerment Programme)
 Specific health interventions (adapted from existing life skill
education module)

45. Several discussion sessions were held with the respective class teachers
of the selected schools, and priority areas for LSE were identified
From an exhaustive list of identified choices for domains of
intervention, the experts of Community Medicine and experts of
Education identified a limited number of individual empowerment-
specific domains
Intervention module was prepared on the basis of the priorities

47. Domains:
Nutrition
• ‘Healthy and unhealthy food’ was renamed as ‘I
decide my food, I decide my health’
• Names of foods were changed based on local food
availability and dietary practices
Health and
hygiene domain
• Intervention related to hand washing was retained
• Goal setting and achieving for increasing the motivation of the
students towards a goal-directed life approach and it was included
from the AGEP module

48. • All the modules, charts and handouts were translated into Bengali
and culturally adapted by bilingual experts
• Sessions ranged from 45 to 120 min
• The intervention was administered by K.S. following training by
A.D. and M.P.S.
• To ensure 100% attendance of the students, attendance was made
compulsory on the intervention days by school authorities
(Details about the intervention was given)

49. DATA COLLECTION
• At baseline, all the students were surveyed by K.S.
• Data regarding primary outcome were obtained from students of the
pretested group only
• All students of the experimental groups were also examined with SDQ
• Data regarding academic performance were obtained for all students at
baseline

50. • Post-intervention data individual resilience, self-determination and
HLC were obtained at 3 months of follow-up from all the four groups
• Data regarding the strength and difficulties of the experimental group
students were obtained at the same time
• Section-wise examination was conducted within the classrooms in
sessions similar to pre-test sessions
(data collection well described)

51. • Bivariate correlations obtained for all independent variables with pre-
test resilience scores
• Standard statistical analysis plan to determine the effect of intervention
and pre-test on primary outcome (Braver and Braver, 1988)
• Multi-level mixed effect general linear modelling
STATISTICALANALYSIS

52. • Random effect of ethnicity nested within each class of study in
addition to considering the fixed effect of ethnicity to obtain an
adjusted effect averaged for the population
• Path analysis performed to determine the direct and indirect effects of
intervention on resilience taking:
 Pre-test scores of resilience, internal HLC, self-determination
and intervention as exogenous variables

53.  Post-test scores of internal HLC and self-determination as
endogenous variables
 Post-test scores of resilience as outcome variables
• Statistical analysis was performed using STATA 13
• Repeated measure ANOVA was performed in SPSS v20
• overall and ethnicity- and sex-stratified marginal means of resilience
before and after intervention (unadjusted and adjusted for baseline
variables) were plotted
(adequate and appropriate)

54. ETHICAL ISSUES
Not well addressed:
• Assent
• Approval from ethics committee
• Registration no. not mentioned
For ethical reasons, all students of each school were included in the
study population

68. Bivariate correlations:
• At baseline, all exogenous and endogenous variables considered in this
study had statistically significant association with resilience factors,
except type of family and age of students, generally in the expected
directions
• For example, greater levels of violence experienced were associated
with lower resilience

69. Pre-test sensitization:
• In 2-way ANOVA to determine the main effect and interaction effect
of the two factors (i.e., pre-test and intervention), only the intervention
effect was statistically significant on the post-test scores
• Mean difference of estimated marginal means between the intervention
and non-intervention group was 12.86 (p < 0.001)

Fig. 2. Structural equation model showing effects of intervention on resilience, self-determination and internal HLC
* Only significant paths has been shown

77. • In line with the objectives
• Some table column headings missing
• Figures are self explanatory
• Footnotes are given
• All statistical analysis has been done
• Number of participants (n) for intervention and control group given

78. STRENGTHS:
• Solomon's four-group design used to avoid the bias of pre-test
sensitization
• 100% participation rate by the students throughout the intervention

79. LIMITATIONS:
• First stage sampling was limited to only two community development
blocks because of limitation of resources
• Students were allocated to different groups through section-wise
allocation, which was a non-random allocation

80. • Data on family climate-related variables were based on self-reports
of the adolescents, which may be exaggerated/under-reported
• Academic performance of the students was measured using record
of school performance only, which may contain recording errors
(strengths and limitations well addressed)

81. • LSE-based health empowerment intervention successfully increases
resilience and two important resilience characteristics, self-
determination and HLC
• Reduces the gap in resilience between tribal and non-tribal
adolescents
CONCLUSIONS
(conclusions are in line with objectives)

82. RECOMMENDATIONS:
• Quality-assured training of the teachers and quality control of
intervention
• Study informs the existing health policy that school mental health
services should be coupled with developmental activities
• Follow-up study to determine washout period of effect of intervention
(specific, doable but not derived from study findings)

83. FUNDING
CONFLICT OF INTEREST
(Funding details and conflict of interest has not been
declared by the authors)

84. GENERALIZABILITY
Generalizable in similar setting

85. What I Learnt?
• Solomon group four design
• Resilience
